This is a wonderful example of the denseness of Seoul. See that two foot alleyway on a steep-ass hill? See those signs? Each of those are businesses, at least one of them is a restaurant. I can tell because there's one of those bloody red and white scooters at the bottom of the hill. Pretty much any "walk in and gnosh" establishment delivers and does so for free. It's some poor schmuck's job to hop on a scooter while carrying a suitcase sized aluminum food tray and rip down the road/sidewalk/park/hallway to get it to you. Amazing service, but I really wish they didn't play "Make the white guy shit his pants in fear." so much.
